Raise rent by a modest amount, on time and in writing, to a number your tenant can check against the market. Most good tenants accept an increase like that. What sends them looking is a surprise: a big jump, short notice, or a new rent well above what nearby units cost.
The math that should set your increase
A tenant leaving costs more than most increases earn.
Rent is $1,800. A 4% increase adds $72 a month, or $864 over a year.
If the tenant leaves instead, a typical turnover might cost a vacant month ($1,800), cleaning and paint ($700), small repairs ($400) and listing and showing time ($300): about $3,200.
That is nearly four years of the $72 increase. An 8% increase would bring in $1,728 a year, but only if it doesn’t cost you the tenant.
So set the number from two sides: what similar units rent for now, and what it would cost to replace this tenant. An increase that brings rent to just under market is often the sweet spot.
Step 1: Know the market
Pull three to five comparable listings and recent rentals. If the unit rents at $1,800 and comparables go for $1,900 to $1,950, a 4% raise to $1,872 still leaves the tenant under market, and they can see it for themselves. If comparables go for $1,800, a raise needs a better reason than “everyone else is raising rent.” The guide to how much to charge for rent walks through pricing from comparables.
Step 2: Check the law where you rent
- During a fixed-term lease, you usually can’t raise rent unless the lease has an escalation clause. The new rent starts at renewal.
- A month-to-month tenancy can change with written notice. Thirty days is the most common minimum, but several states ask for more, and a few cap the raise:
| State | Notice before a month-to-month increase | Statewide cap |
|---|---|---|
| Most states | 30 days | None |
| California | 30 days, or 90 for more than 10% in a year | 5% plus inflation, up to 10%, on many units |
| Oregon | 90 days, and none in the first year | 7% plus inflation, up to 10% (9.5% for 2026) |
| Washington | 90 days, and none in the first 12 months | 7% plus inflation, up to 10% (9.683% for 2026) |
| New York | 30, 60 or 90 days for 5% or more, by length of stay | None; local rules in New York City |
The caps don’t reach every home. Newer buildings are exempt, and so are some others. Some cities add rent control or rent stabilization on top. The rent increase notice by state table gives every state’s rule and statute, with a page for each state, such as California’s rent increase rules.
Step 3: Give more notice than the law asks
For a lease renewal, send the offer 60 to 90 days before the lease ends, even where 30 days is the legal minimum. It gives the tenant time to plan and less reason to shop around, and it tells you early if they plan to leave.
The lease ends on Thursday, December 31, 2026, at $1,800. On Thursday, October 1, 91 days ahead, the landlord offers a renewal at 4%: $1,872 a month from Friday, January 1, 2027.
The rent increase calculator shows the new rent, the yearly change and the first day it can start. The rent increase notice puts it into a dated letter and checks the notice period for your state.
Step 4: Say it well
A good increase letter is short:
- The current rent, the new rent and the change in dollars: “from $1,800 to $1,872, an increase of $72 a month.”
- The date the new rent starts.
- A one-line reason, if there is a real one: higher property taxes and insurance, or market rents.
- Options, if you can offer them: 12 months at 4%, or 24 months at 3.5% a year.
- Thanks, and how to reach you with questions.
Don’t apologize, and don’t argue. A calm number with a reason reads as fair.
When the tenant pushes back
Treat a reply as a good sign: a tenant who negotiates wants to stay. Ask what number works for them and why, then weigh it against the turnover cost.
The tenant counters at 2%: $1,836 instead of $1,872. The gap is $36 a month, or $432 over the year. Against a $3,200 turnover, meeting in the middle at 3% ($1,854) is an easy call, and a 24-month lease at 2% may be better still.
Other trades that cost you little: a start date a month later, an increase in two smaller steps six months apart, or the lower number in exchange for a longer lease. Put whatever you agree in the renewal or in a signed lease addendum.
What keeps a tenant besides the price
- Fix things fast in the months before the renewal. The increase letter is read against the last repair request.
- Offer a small upgrade at renewal. A new faucet, fresh paint in one room or a ceiling fan can soften a raise.
- Prefer steady, modest increases to a large catch-up after years without one. Tenants plan for 3% a year; 15% at once sends them to the listings.
- Trade a longer lease for a smaller increase. Two years with no turnover is worth more than a slightly higher rent for one.
What not to do
- Don’t raise rent to punish. An increase soon after a tenant asks for repairs, calls an inspector or joins a tenants’ group looks like retaliation, which most states forbid.
- Don’t treat tenants differently because of race, color, religion, sex, national origin, disability or children in the household. The same reasoning should apply to every unit.
- Don’t skip the paperwork. An increase without proper written notice may not take effect, and the tenant can keep paying the old rent until it does.

Questions people ask
How much can a landlord raise rent?
In most states there is no limit on a raise at renewal, as long as the notice is proper and the increase is not retaliation or discrimination. California, Oregon and Washington cap yearly increases on many homes, and some cities have rent control or stabilization.
How much notice is needed for a rent increase?
For a month-to-month tenancy, 30 days’ written notice in most states. Oregon and Washington require 90 days, California 90 for a raise of more than 10%, and New York up to 90 for longer tenancies. A fixed-term lease usually changes only at renewal.
Is it better to raise rent a little every year?
Usually, yes. Small, steady raises track costs and the market, and tenants can plan for them. Skipping a few years and then asking for 15% at once is the increase most likely to send a good tenant looking.
